Devon is known for the Devon Horse Show, the oldest and largest outdoor multi-breed horse competition in the United States. The event is held in late May to early June and lasts ten days. In 2016 the event is held from Sep 27 to Oct 2.

It was also home to the Valley Forge Music Fair from 1955 to 1996, hosting hundreds of famous musical and comedy acts.

Hilltop Park, with a Devon address but outside of the Devon CDP, is operated by the township government.[4][6] It has a pavilion with toilets, a picnic area, two soccer fields, a "tot lot", and trails for walking purposes.[6]
